Investigating the Dynamics of Sex‐Structured Stock Assessment Models Under Sexual Size Dimorphism

Fisheries Management and Ecology, EarlyView.
ABSTRACT The integration of separate sexes in stock assessment models represents an advancement towards more realistic modeling of interactions between fisheries and target species. However, increased model complexity can also introduce additional uncertainty into the modeling process.

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

Fisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

When mesophotic meets shallow: First records of deep‐associated reef fishes in a well‐studied tropical bay under the influence of spring–summer upwelling

Journal of Fish Biology, EarlyView.
Abstract We document the first records of reef fishes typically associated with mesophotic environments on shallow (<10 m) coral reefs inside a well‐studied tropical bay. The vermilion snapper Rhomboplites aurorubens and the pygmy angelfish Centropyge aurantonotus, usually restricted to deeper (>40 m) shelf habitats along the Brazilian coast, were ...

Cryptobenthic reef fishes may not be safe from invasive lionfish (Pterois spp. Oken, 1817)

Journal of Fish Biology, EarlyView.
Abstract Lionfish (Pterois spp.) are hypothesized to negatively influence cryptobenthic reef fish assemblages through predation. We evaluated these potential effects on Caribbean reefs in Costa Rica and tropical reefs in Brazil. Brazil provided a reference condition for cryptobenthic assemblages prior to lionfish invasion, while the Costa Rica sites ...

Ontogenetic Development of Hyperostosis in the Crevalle Jack Caranx hippos (Linnaeus, 1766) and New Records of Affected Bone Regions

Journal of Fish Diseases, EarlyView.
ABSTRACT Hyperostosis is a non‐pathological condition widely reported in marine teleosts, yet its developmental dynamics and underlying drivers remain poorly understood. This study investigates the ontogenetic progression and anatomical distribution of hyperostosis in Caranx hippos based on a growth series of 39 specimens collected along the Brazilian ...
